Abstract
An information processing device comprising a projection control unit that controls projection of drawing information, the projection being performed by a projection device, on a basis of ratio information between a first distance and a second distance, the first distance being acquired from sensing information regarding a drawing tool and being from a reference point to the drawing tool, and the second distance being from the reference point to an intersection point between a straight line connecting the reference point with the drawing tool and a calibration plane.
